Fabio Estevam 9a8804a85e wandboard: Add board revision detection support
There are two revisions of wandboard: version B1 and C1.

Add the revision detection support, so that the correct dtb file can
be automatically loaded.

Based on the patch from Richard Hu <hakahu@gmail.com>.

U-Boot for Wandboard
--------------------

This file contains information for the port of U-Boot to the Wandboard.

Building U-boot for Wandboard
-----------------------------

To build U-Boot for the Wandboard:

$ make wandboard_config
$ make

Flashing U-boot into the SD card
--------------------------------

- After the 'make' command completes, the generated 'SPL' binary must be
flashed into the SD card;

$ sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync

(Note - the SD card node may vary, so adjust this as needed).

- Flash the u-boot.img image into the SD card:

sudo dd if=u-boot.img of=/dev/mmcblk0 bs=1k seek=69; sync

- Insert the SD card into the slot located in the bottom of the board (same side
as the mx6 processor)

- Connect the serial cable to the host PC

- Power up the board and U-boot messages will appear in the serial console.
